IMPROVEMENT IN SCRUBBING DEVICES.

Specification forming part of Letters Patent No. 207,108, dated August20, 1578; application filed March 9, 1878.

To all whom it may concern:

Be it known that I, ANDREW J. DAVIS, of the village of Hartford, countyof Van Enron, and State of Michigan, have invented a new and usefulImprovement in a Mop, Wringer, and Scrub-Brush Combined, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention is an improvement in implements for household use. Itconsists, essentially, of a wrin ger composed of a windlass and rollerand an apron-shaped mop, to be used in connection with a scrubbing-brushoperated by a wheel and gear-wheels when said parts are applied to amain frame attached to an ordinary brush-handle.

The devices are so arranged that when the scrubbing is being performedthe floor may be rubbed by the mop to absorb the water, &c., andafterward the mop may be passed between rollers to wring it and prepareit for use again. It consists generally of a rectangular frame attachedto an ordinary handle, with jaws extending from it at its lower end, toserve as journal-bearings to the shaft of a rotary scrubbing-brush. Aplate to which the jaws to support the brush are fastened is sofashioned as to clasp the end of the rectangular frame, and, extendingdownward, forms journal-bearin gs for a shaft, on one end of which is aplain wheel, and on its opposite end a spurwheel, which engages a pinionto move the rotary brush. Immediately behind the rotary brush is a bar,which forms the end of the rectangular frame before mentioned, whichserves as a hold to the end of the mop secured thereon. The mop is of anapron shape, and is secured at the opposite end to a Windlass fixed in asecond frame. This frame is also rectangular, and is provided withprojecting lugs with loops to clasp the first frame, ouwhich it slides.Immediately behind the Windlass is a roller fixed in a third frame,which moves 1ongitudinally in slots on either side of the second frame.Between the transverse plate of the third frame and the inner plate ofthe second frame is a spiral spring, regulated in its compression by ascrew, which adjusts the roller to the proper distance from theWindlass. The mop passes between the roller and Windlass, and issqueezed or wrung, as before stated.

In my drawings, Figure l is a side elevation of the combined device.Fig. 2 is a plan View of the same.

Similar letters of reference denote like parts in all of the figures.

Referring to drawings, A is the rectangular frame, composed of rods ofsuitable material, secured in the handle B. O G are jaws attached tobent plate A, which serve as bearings to the journals of the rotarybrush D.

This brush is cylindrical inform, and provided with bristles fixed inits periphery in the usual manner. In the second rectangular frame, E,which isformedof plate or sheet metal, is hung in suitablejournal-bearings a Windlass, I provided with a crank, j. About the axleof this Windlass is wound an apronshaped mop, G. The mop-cloth issecured to the bar or axle of the Windlass at one end and to the lowerbar of the frame A at the other.

H is the roller, journaled in the frame I. This frame has a longitudinalmovement in the frame E, and is guided in this movement by slots hformed in said frame E. The frame E has four loops, k, extendinglaterally from its transverse plates, which fit over the long bars offrame A, on which they slide, for the purpose hereinafter described.

Between the plate b of frame E and the transverse plate g of frame I isa spiral spring, f, which encircles a rod, 0, and serves to keep rollerH bearing against the mop-cloth as it is rolled on Windlass F. A nut, 0,secured to sleeved, serves to adjust the spiral spring f to a suitablecompression. In the bent plate A is hung a shaft, which has on one endawheel, f, which bears on the fioor when the scrubber is in use, and onthe other a spur-wheel, m, which gears with a pinion, 12,011 the end ofthe shaft, forming the axle of the rotary brush. In the handleB is aspring-latch, i, which holds the frame E back when the rotary brushalone is in use.

In operating my device I slide the frame E back over the frame A untilit is c ght automatically by the latch. With the h dle V of the devicein the hands of the operator, and

the brush on the surface to be cleansed, movement is given back andforth, when the wheel f, also bearin g on the surface being scrubbed,moves and carries the spur-wheel, and with it been properly wrung theframe may be drawn back and secured, and the brush used again, asdescribed.

What I claim as new, and desire to secure by Letters Patent, is-

The interchangeable mop, wrin ger, and scrubbing brush, consisting,essentially, of the wringer composed of Windlass F and roller H, incombination with mop G and scrubbingbrush D, operated by wheel f andgear-wheels m u when said parts are applied to frame A, as and for thepurpose set forth.
